Magnetic field reversal is a fascinating topic. You are brought up to think that the compass, pointing to the north, is an ...

March 2026 could be the best month for the northern lights until the mid-2030s, as celestial mechanics and solar activity combine for potentially potent results.

Earth’s magnetic shield is shifting in dramatic ways. New data from ESA’s Swarm satellites show that the South Atlantic Anomaly — a vast weak spot in Earth’s magnetic field — has grown by nearly half ...

Earth’s magnetic field is often described as a steady shield, but the geological record tells a more restless story. Polarity flips, when magnetic north and south swap places, happen several times per ...

Webb maps Uranus’s upper atmosphere, revealing cooling temperatures, shifting auroras, and the effects of its tilted magnetic field.

We are all very familiar with the concept of the Earth's magnetic field. It turns out that most objects in space have magnetic fields but it's quite tricky to measure them. Astronomers have developed ...

Our planet’s magnetosphere has seen dramatic shifts across its history—even total reversals—but this recent wrinkle doesn’t pose a threat to life Earth’s magnetic field surrounds the planet, with ...

Apollo moon rocks show the Moon had short bursts of strong magnetism, not a long lasting magnetic field, changing how we ...

Scientists have developed a way to produce models of where the magnetic field lines are several times each day. Here we have created a time-lapse version of these models over four days (2-3 each day) ...

The traditional method for visualizing magnetic fields, which your science teacher probably demonstrated at some point, is to sprinkle some iron filings onto a piece of paper and hold it over a magnet ...
